AbstractGeochemical data from 155 spring locations within the remote 37,000 km2 South Nahanni River basin of the Mackenzie Mountains, Northwest Territories, were used to evaluate the economic mineral potential of the region, an area proposed for a national park designation. Trace element analyses were evaluated using three different approaches (the sum of trace element concentrations as a percentage of total dissolved solids, identifying individual anomalously high trace elements, and the inverse use of the Ficklin Diagram). Two out of the three approaches detected the two known deposits of the area, Prairie Creek and Tungsten, but not with the same method in each case, indicating that a multi-pronged approach is best. The springs were determined to be elevated in trace elements in comparison to waters related to mining deposits around the world. Silica geothermometry determined the average depth of circulation of the springs to be 2.1 km for warm or hot springs, and ranging from 4.7 km to less than 200 m for the entire dataset, which is indicative of the
accessibility of the predicted mineralized zones. These simple statistical and graphing methods can successfully identify mineralized zones quickly and efficiently in a largely under-explored area.
